Well, I meant it as $400 for one halide, and two times $400 for two Ecoxotics, so the uplift is only the difference $400 and it's only the uplift that you want to look at when comparing that against the energy savings over time.
It's hard to do a completely fair comparison because you can get considerable savings by buying used in either case, except that there will be more halides available second hand right now (over time surely there will be more options for the LEDS as people shift hardware around or shutdown tanks, etc., but for now, there probably aren't many available second hand); and then you can also take into play that DIY options for LED and halides tend to yield lower costs up front (but then we're comparing two completely different things altogether).
One can reasonably expect to replace halides on a 12 month interval but I'm curious as to the true longevity of the LED units, is it reasonable to expect 0% replacement of LEDS over 60 months? And if there is the occasional dud LED out of a fixture, how easy will that be? I think only time can tell for sure but at least the theory is that the effective lifespan is closer to 5 years.
